Threshold characteristics of non-resonator laser generation in dye solutions with ZnO nanoparticles

Abstract

An experiment was carried out to determine the generation thresholds in solutions of the Rhodamine 6G dye with Au nanoparticles having a plasmon resonance at the pump wavelength and ZnO nanoparticles not having a plasmon resonance. It was shown that solutions with ZnO nanoparticles have lower lasing thresholds in comparison with solutions with Au nanoparticles.
